Look what I discovered in my animation program Lightray 3D
Click me!
The program has a function to create human bone structures just by entering some numbers and press a button
I don't know if the scaling is alright like this but this is just to show the principle anyways! Don't know If I will ever be able to create believable animations for humans...
But since the current animations are crap and years old, the best way to do is send them to hell and start news from scratch
If I don't succeed at all, Levaravel still can try it, I heard that there's an md5 plugin for Lightwave as well.
Next thing for me to do: Think about new bone structures for the fps view and the world model

Animating weapons is much easier and it's certain that I can at least do that !
